"We will have to make decisions in this case at the end of the season. We may decide on economical factors.

"Would it be best to cash in a big fee? Or would it be even better to keep Lewandowski to ensure we are more likely to qualify for the Champions League with him in our side, as this would guarantee us big income?

"It's a decision we will have to take. It's our decision. It's not something to be decided by others."
